Multi-scale Entanglement Renormalization Ansatz in Two Dimensions: Quantum Ising Model
Abstract
We propose a symmetric version of the multi-scale entanglement renormalization Ansatz (MERA) in two spatial dimensions (2D) and use this Ansatz to find an unknown ground state of a 2D quantum system. Results in the simple 2D quantum Ising model on the 8×8 square lattice are found to be very accurate even with the smallest non-trivial truncation parameter.
